peace-maker e88054fe49 Start to check type hints gradually (#2714)
* Start to gradually add type hints

Use mypy-baseline to ignore all existing errors for now while avoiding adding new ones in new code.

* Remove Python 2 fallback imports

* Remove py2compat layer

* Avoid redefining a tube helper function

* Remove explicit new-style class (object) syntax

old-style classes were removed in Python 3 so there is no distinction anymore.

* Ignore type error in shellcraft helper script

* Fix repeatedly changing `linux_dirent.d_name`

* Avoid typechecking windows_termcap on Linux

We run mypy on Linux in CI, ignore Windows related import errors

* Run mypy-baseline in CI

* Add type hint plan to CONTRIBUTING

* Sort the mypy baseline

Run with `--sort-baseline` for better diffs.

`mypy | mypy-baseline sync --sort-baseline`

* Switch dev dependencies to dependency-groups

The dependency groups aren't baked into build metadata and won't appear on Pypi.

pwntools - CTF toolkit

PyPI Docs GitHub Workflow Status (dev) Coveralls MIT License Packaging status Discord Twitter

Pwntools is a CTF framework and exploit development library. Written in Python, it is designed for rapid prototyping and development, and intended to make exploit writing as simple as possible.

from pwn import *
context(arch = 'i386', os = 'linux')

r = remote('exploitme.example.com', 31337)
# EXPLOIT CODE GOES HERE
r.send(asm(shellcraft.sh()))
r.interactive()

Documentation

Our documentation is available at docs.pwntools.com

A series of tutorials is also available online

To get you started, we've provided some example solutions for past CTF challenges in our write-ups repository.

Installation

Pwntools is best supported on 64-bit Ubuntu LTS releases (22.04 and 24.04). Most functionality should work on any Posix-like distribution (Debian, Arch, FreeBSD, OSX, etc.).

Pwntools supports Python 3.10+ since version 5.0.0. Use Pwntools 4.x for older versions as well as Python 2.7. Most of the functionality of pwntools is self-contained and Python-only. You should be able to get running quickly with

sudo apt-get update
sudo apt-get install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade pwntools

However, some of the features (assembling/disassembling foreign architectures) require non-Python dependencies. For more information, see the complete installation instructions here.
